Drawing a TF1, one way works, the other doesn't!

ROOT

Hi everyone,

I’m trying to figure out why this doesn’t produce the same output.
Essentially in one case the TF1 is declared in the usual fashion, in the other it is declared through a function. The black rate is correct, the green is wrong. I can’t find a mistake, could it be a root bug?

Hi,

try using only floats in your exponents (i.e. 1./3. instead of 1/3).
